What are the technical characteristics of medium and low temperature denitrification catalysts?

1. The production process of medium and low temperature denitration catalysts is advanced and reasonable, with all materials mixed as a whole and formed in a secondary manner. The amount of active ingredients is large and evenly distributed in the carrier, significantly improving catalytic activity and strong anti poisoning ability. Even if the catalyst surface is worn, it will not lose its activity;

2. The honeycomb catalyst as a whole is a ceramic homogeneous material, with a significantly lower thermal conductivity than the metal substrate, and there is no thermal expansion difference in the catalyst body, so it has different heat resistance and can better adapt to temperature fluctuations when the unit load changes;

3. Honeycomb catalysts have a larger surface area, resulting in a larger contact area between flue gas and catalysts. Under the same engineering design conditions, the amount of catalyst used is relatively small;

4. The medium and low temperature denitration catalyst has a different distribution of flue gas flow field, and the pressure drop during flue gas circulation is relatively small;

5. Under the same operating conditions and dosage, the replacement cycle of honeycomb catalysts is longer, and the operating and maintenance costs throughout their entire lifespan are lower.

(1) Improved to nano catalyst powder, improving electron mobility and enhancing denitrification efficiency

(2) Adding auxiliary catalysts and catalyst products has improved the efficiency of powder activity and denitrification performance

(3) Manganese was added to the catalyst supported by TiO2, which improved the low-temperature denitrification characteristics

Manufacturer of SCR denitration catalyst for sintering machine: The flue gas temperature at the back of the boiler is lower than that of coal-fired power plants, so it often operates at partial load, requiring a heater and increasing fuel costs. And this type of catalyst can meet the needs of low-temperature denitrification without incurring additional costs.

Manufacturer of SCR denitration catalyst for coke oven: Due to the use of high sulfur coal or coal with high dust, the temperature at the rear of the boiler is more than 30 degrees lower than normal. Therefore, under partial load conditions, using plate catalysts may prevent the denitration equipment from starting; The medium and low temperature denitrification catalyst can meet the requirements for denitrification reaction under this condition.
